Question about 2004 Audi A6 2.7
- can this be from drops in voltage - I notice the my voltage drops at an idle when the ac/heat on or defroster is turned on
Yes if the battery is completely shot & just barely
starts the car
You need professional tools to check for enhanced codes,
when it comes to abs system
You need to check the alternator out for voltage,current
& a/c current ripple,that could be your voltage issues
I would guess the abs/trac is another problem
When the a/c is on, the alternator should hold the field current
on longer & the idle should come up as well, if the cars computer
has control over things

Something happened to me today... I was driving my car and my trac control and abs were on.... I put my car in reverse and got out of a parking... And the traction control and abs went off... What could that be?
